Molecular in vitro diagnostic examinations - Specifications for pre-examination processes for formalin-fixed and paraffin-embedded (FFPE) tissue - Part 3: Isolated DNA (ISO 20166-3:2018)

This document gives guidelines on the handling, documentation, storage and processing of formalin-fixed and paraffin-embedded (FFPE) tissue specimens intended for DNA examination during the pre-examination phase before a molecular assay is performed.
This document is applicable to molecular in vitro diagnostic examinations including laboratory developed tests performed by medical laboratories and molecular pathology laboratories. It is also intended to be used by laboratory customers, in vitro diagnostics developers and manufacturers, biobanks, institutions and commercial organizations performing biomedical research, and regulatory authorities.
NOTE       International, national or regional regulations or requirements can also apply to specific topics covered in this document.

Molekularanalytische in-vitro-diagnostische Verfahren - Spezifikationen für präanalytische Prozesse für formalinfixierte und paraffineingebettete (FFPE)-Gewebeproben - Teil 3: Isolierte DNS (ISO 20166-3:2018)

Dieses Dokument dient als Leitfaden zur Handhabung, Dokumentation, Lagerung und Verarbeitung von aus FFPE Gewebe bestehendem und für die DNA Untersuchung vorgesehenem Untersuchungsmaterial während der präanalytischen Phase vor Beginn der molekularen Analyse.
Dieses Dokument gilt für molekulare in vitro diagnostische Untersuchungen, wozu auch im Labor entwickelte Prüfungen zählen, die von medizinischen Laboratorien und Laboratorien der molekularen Pathologie durch¬geführt werden. Sie soll auch von Laborkunden, Entwicklern und Herstellern von In vitro Diagnostika sowie Biobanken, Einrichtungen und kommerziellen Organisationen, die in der biomedizinischen Forschung tätig sind, und Aufsichtsbehörden eingesetzt werden.

Analyses de diagnostic moléculaire in vitro - Spécifications relatives aux processus préanalytiques pour les tissus fixés au formol et inclus en paraffine (FFPE) - Partie 3: ADN extrait (ISO 20166-3:2018)

Le présent document fournit des lignes directrices concernant la manipulation, la documentation, le stockage et le traitement de prélèvements de tissus fixés au formol et inclus en paraffine (FFPE) destinés à l'analyse de l'ADN durant la phase préanalytique précédant la réalisation d'une analyse moléculaire.
Le présent document s'applique aux analyses de diagnostic moléculaire in vitro, y compris les analyses développées en laboratoire, réalisées par des laboratoires de biologie médicale et des laboratoires de pathologie moléculaire. Il est également destiné à être utilisé par des clients de laboratoires, des développeurs et fabricants de l'industrie du diagnostic in vitro, ainsi que par des biobanques, des institutions et des organismes commerciaux spécialisés en recherche biomédicale, de même que des autorités de réglementation.
NOTE       Des réglementations ou exigences internationales, nationales ou régionales peuvent également s'appliquer à des sujets spécifiques traités dans le présent document.

Molekularne diagnostične preiskave in vitro - Specifikacije za predpreiskovalne procese za tkiva, ki so fiksirana v formalinu ter položena v parafin - 3. del: Izolirani DNK (ISO 20166-3:2018)

Ta mednarodni standard vsebuje priporočila za obravnavo, dokumentiranje, shranjevanje in obdelavo vzorcev tkiv, ki so fiksirana v formalinu ter položena v parafin (FFPE), namenjenih za analizo DNK med predpreiskovalno fazo, preden se izvede molekularni preskus. Ta mednarodni standard se uporablja za molekularne diagnostične preiskave in vitro, vključno z laboratorijsko razvitimi preskusi, ki jih izvajajo v medicinskih laboratorijih in laboratorijih za molekularno patologijo. Uporabljali naj bi ga tudi uporabniki laboratorijev, razvijalci in proizvajalci diagnostike in vitro, nanaša pa se tudi na institucije in komercialne organizacije, ki izvajajo biomedicinske raziskave, biobanke ter regulativne organe. Celovitost DNK v tkivih se lahko spremeni pred fiksacijo v formalinu, obdelavo in shranjevanjem ter med temi postopki. Kemijske spremembe DNK med fiksacijo tkiva lahko privedejo do fragmentacije in sprememb zaporedja, sprememb v stanju metilacije ali celo strukturnih sprememb, kar lahko vodi do npr. lažnih sprememb števila kopij pri primerjalni genomski hibridizaciji z uporabo mikromrež (aCGH). Te spremembe molekul DNK lahko vplivajo na veljavnost in zanesljivost rezultatov preskusov preiskav. Zato je nujno treba sprejeti posebne ukrepe, da se zmanjšajo opisane spremembe za nadaljnje preiskave DNK. OPOMBA:   Za določene teme, ki so zajete v tem mednarodnem standardu, lahko veljajo tudi mednarodni, nacionalni ali regionalni predpisi ali zahteve.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
